DNS drop out

[#1]

checked the log of the checkdns script and these are the error lines, just spotted a small error in the code - it is not checking 212.159.6.10, but 212.159.6.9 twice. Now correct the error and will keep monitoring.

used

grep 'error' checkdns.txt

to list out just the error times

Setup a new check process on a Pi connected directly to the router, so far no errors

Thanks David, let me know how it goes.

Those latest results don't look as conclusive so it would definitely be helpful to rule out the Wi-Fi element.

Just to clarify: DHCP is disabled on all additional access points, yes?

How have things been recently @dallday?

@dallday - FYI, we're probably going to close the investigation at this side unless there's any progress to share?

Let me know if things are still in a state where we can do some more digging.
